In April 2011, prosecutors say, Susan Loper, 40, was kidnapped from her Pilates studio where there was a struggle. The victim was killed and her body was dumped along the Dallas North Tollway. She was found a day later.

Terrance Deering Black, 50, faces an automatic life sentence if he is convicted in the capital murder trial that could last up to three weeks.

Prosecutors intend to show that Black kidnapped and killed Loper on April 19, 2011, before heading to Arizona, where he jumped off the rim of the Grand Canyon while running from park rangers.
